Rock layers were found containing 30 kg of radioactive elements that had a half life of 5 million years. How old were the rock layers
scientists determined that the samples had originally contained 120 kg of the radioactive materials?
A 10 million years old
B. 5 million years old
C. 15 million years old
The rock layers that the scientists determined had originally contained 120 kg of the radioactive materials were 10 million years old. Thus, the correct answer is option A.
What is a radioactive element?Radioactive elements are unstable atomic nuclei that undergo radioactive decay to form stable nuclei due to the presence of excess nuclear charge within them. The neutron to proton ratio can be used to estimate the stability of an element's nuclei.
Stable nuclei with atomic numbers up to Z= 20 have an equal number of protons and neutrons. The repulsion forces between protons increase as the atomic number increases.
The radioactive element content of granite, rhyolite, and tuff is comparable. The very coarse-grained granitic rock known as pegmatite contains a high concentration of radioactive minerals.
Therefore, the rock layers scientists determined that the samples had originally contained 120 kg of the radioactive materials were 10 million years old.
